OIL-BURNER.

Specification of Letters Patent.

Patented Oct. 15, 1907.

Application filed June 7, 1906. Serial No. 321,042.

burner for heating and other purposes of simple, durable and inexpensiveconstruction, in which the flow of oil into the combustion chamber andthe flow of air into the same can be controlled by mechanism providedfor the purpose.

With these objects in view, my invention consists in certain details, inthe construction, arrangement and combination of the various par-ts ofthe device, whereby the objects contemplated are attained, ashereinafter more fully set forth, pointed out in my claim andillustrated in the accompanying drawings, in which- Figure 1 is-a sideelevation of the burner. Fig. 2 is a vertical, sectional view of thesame, Fig. 3 is a'plan view of the burner, and Fig. 4 is a sectionalview out on the line 4-4 of Fig. 2.

Referring to the accompanying drawings, it will be seqn that I haveprovided a cylindrical combustion chamber 10, having the enlarged lowerportion 1'1 therein. Secured to the lower edge of the enlarged lowerportion 11 of the combustion cylinder 10 are the burner supports 12 and13, to which the hollow cylindrical body portion 14 of the burner isdetachably secured. On the interior of the hollow body portion 14 is theoil chamber 15 which diminishes in size to form a comparatively smalloutlet 16, through which the oil is designed to pass. In the lowerportion of the cylindrical body 14 we have provided a nut 17, designedtobe screwed into the lower end of said body portion. A slight distanceabove the nut 17 is a cap 18. Between the cap 18 and the nut 17 I haveprovided a packing 19 designed to prevent the leaking of the oil fromthe chamber 15.

Passing through thecap .18 and the packing 19, and screwed into thecentral portion of the nut 17 is an adjustable screw valve 20 having asmall wheel 21 at its lower end by which it can be operated, adjacent tothe upper end of which I have provided a guide 22 through 'which thescrew valve passes. Near the upper end of the screw valve I haveprovided'a tapered portion 23, and immediately above thistaperedportion, a mixer pin 24, which mixer pin is designed to pass through theoutlet 16 and to have the oil pass around it as it is forced through theoutlet. The tapered portion 23 is designed to entirely close the outletwhen forced into it by closing the screw valve.

By regulating the screw valve and through it the mixer pin 24, themixing of the oil is regulated. Leading into the chamber 15 is an oilsupply pipe 25, through which the oil is forced by a suitable mechanismfor creating sufficient pressure to provide an even flow of oil into thecombustion chamber.

At diametrically opposite points on the rim of the enlarged portion 11of the combustion chamber, I have provided screws 26 and 27, and on thescrew 26 I have mounted the slide 28 which has a slot 29 in which is thescrew 26. I have provided a handle 30 designed to m ve the slide 28outwardly or inwardly on the screw 20. I have provided a similar plate31 having the slot 32 in it in which is the screw 27, and I have alsoprovided a handle 33 for operating the slide 31. By moving the slidestoward or away from each other, the

amount of air allowed to pass into the combustion chamber is diminishedor increased so that by the use of my mechanism, absolute control is hadover the admission of air and oil into the combustion chamber. In

, constructing this device, various materials may be used and the devicemay be varied somewhat to accomplish the desired results. i i

In practice, this burner can be used to advantage in brick kilns, and itcan also be used to advantage in con nection with'boilers, furnaces andother numerous devices in which burners are beneficial.

Having thus described my invention, what I claim and desire to secure byLetters Patent of the United States, therefor is slides arranged andmovable immediately below the said supports and having recesses in theirinner edges conforming in shape to and arranged to receive the burnerand also having slots between the said recesses and their outer edges,and screws extending through said slots and connected \viththecombustion chamber at opposite points.
